Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical connection structure technology, specifically a quick-release electrical connection structure for PCBA boards. Background Technology
[0002] The electrical connection structure of a PCBA board mainly includes the electrical connection method between the PCBA board and the FPC board. Specifically, the PCBA board and the FPC board transmit signals and power through electrical connection;
[0003] Electrical connection methods are further divided into soldering connections (soldering is the most common method for connecting PCBA boards and FPC boards. Solder is typically used to fix the FPC board to the PCBA board, ensuring a stable and reliable electrical connection between the two) and pin connections (in some applications, PCBA boards and FPC boards can be connected via pins. Pin connections provide more stable signal transmission and are easier to replace and maintain).
[0004] To facilitate quick and easy disassembly and maintenance, most existing PCBA board electrical connection structures use pin connections. However, to ensure the stability of the pin connection, a flexible self-locking latch structure is set between the pin connector and the inner side of the connector socket. After the pin connector is inserted into the connector socket, the latch structure can ensure the stability of the connection. However, during disassembly, a certain amount of force needs to be applied manually to pull the pin connector, which is labor-intensive and may cause hand injuries. Furthermore, the latch may break when force is applied during insertion and removal, thus affecting the self-locking stability of the secondary connection and making it unsuitable for use.
[0005] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a quick-release electrical connection structure for PCBA boards. Utility Model Content
[0006] The purpose of this invention is to provide a quick-release electrical connection structure for PCBA boards to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick-release electrical connection structure for PCBA boards, including a connector, grooves on both the left and right sides of the surface of the connector, positioning grooves on the lower side of the inner surface of the grooves near the interior of the connector, a sealing plate on the upper side of the connector, movable grooves in the middle of both the left and right ends of the sealing plate, recessed grooves on the front and back sides of the inner surface of the movable grooves, a common shaft rotatably connected to the inner surface of the recessed grooves, a movable plate fixedly connected to the middle of the surface of the shaft, positioning blocks fixedly connected to opposite sides of the lower surface of the movable plate, and torsion springs fixedly connected to the front and back sides of the surface of the movable plate, with the end of the torsion spring away from the movable plate fixedly connected to the inner surface of the recessed groove.
[0008] Preferably, the area of the sealing plate is the same as the area of the upper surface of the connecting seat, and the thickness of the movable plate is the same as the lateral opening width of the groove.
[0009] Preferably, the lower surface of the positioning block is set as an inclined surface, and the torsion spring is sleeved on the outside of the shaft.
[0010] Preferably, a pin plug is fixedly connected to the center of the lower surface of the sealing plate, and the pin plug consists of an outer covering frame and electrical connection pins inside the frame.
[0011] Preferably, the upper surface of the connector has a socket in the middle, and the size of the pin plug matches the size of the socket.
[0012] Preferably, pin connectors are evenly distributed and fixedly connected to the inner surface of the socket, and the pin connectors correspond to the electrical connection pins inside the pin plug.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This invention utilizes a combination of a groove, a positioning groove, a sealing plate, a movable groove, a countersunk groove, a shaft, a movable plate, a positioning block, and a torsion spring. When the pin plug is inserted into the socket, the movable plate also aligns with the groove. The edge of the groove, utilizing the lower inclined surface of the positioning block, pushes the movable plate, causing the positioning block to rotate and tilt to the left and right via the shaft. This pulls the torsion spring to tighten. Once the pin plug is fully inserted into the socket, the sealing plate completely seals the upper part of the socket, preventing dust from entering and affecting electrical connection stability. At this point, the positioning block aligns with the positioning groove; any gaps in the positioning groove cause the positioning block to lose its limiting position. The torsion spring will rotate back to its original position, thereby causing the movable plate to rotate towards the connecting seat, so that the positioning block is inserted into the positioning groove. Since the upper side of the positioning block is a flat surface and it fits into the positioning groove, the connection structure will not be pulled apart easily, thus ensuring the stability of the connection. When disassembly is required, simply pinch the upper part of the movable plate to rotate the lower part of the movable plate to the left and right, thereby moving the positioning block out of the positioning groove. At this time, simply pull the sealing plate upward to quickly disassemble. The overall structure makes connecting or disassembling very simple and convenient, greatly improving the efficiency of assembly and disassembly, and ensuring the stability of the connection after installation.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] like Figures 1-3 As shown, a quick-release electrical connection structure for a PCBA board includes a connector 1. Grooves 2 are provided on both the left and right sides of the surface of the connector 1. Positioning grooves 3 are provided on the lower side of the inner surface of the grooves 2 near the inside of the connector 1. A sealing plate 4 is provided on the upper side of the connector 1. Movable grooves 5 are provided in the middle of both the left and right ends of the sealing plate 4. Sinking grooves 6 are provided on the front and back sides of the inner surface of the movable grooves 5. The same shaft 7 is rotatably connected to the inner surface of the sinking grooves 6. A movable plate 8 is fixedly connected to the middle of the surface of the shaft 7. Positioning blocks 9 are fixedly connected to the opposite side of the lower surface of the movable plate 8. Torsion springs 10 are fixedly connected to the front and back sides of the surface of the movable plate 8, and the end of the torsion spring 10 away from the movable plate 8 is fixedly connected to the inner surface of the sinking groove 6.
[0021] The lower surface of the positioning block 9 is set as an inclined surface, and the torsion spring 10 is sleeved on the outside of the shaft 7.
[0022] By adopting the above technical solution, the movable plate 8 is inserted into the groove 2. The edge of the groove 2 uses the lower inclined surface of the positioning block 9 to push the movable plate 8 to drive the positioning block 9. Through the rotation of the shaft 7, it rotates and tilts to the left and right sides. At this time, the torsion spring 10 will be pulled and twisted. When the pin plug 11 is fully inserted into the socket 12, the sealing plate 4 completely seals the upper side of the socket 12, thereby preventing dust from entering the socket 12 and affecting the stability of the electrical connection. At this time, the positioning block 9 will be aligned with the positioning groove 3. The gap in the positioning groove 3 will cause the positioning block 9 to lose its limit, that is, the torsion spring 10 will rotate back to reset, thereby driving the movable plate 8 to rotate towards the side of the connecting seat 1, so that the positioning block 9 is inserted into the positioning groove 3. Since the upper side of the positioning block 9 is a plane and is mutually limited and fitted with the positioning groove 3, the connection structure will not be pulled off at will, thus ensuring the stability of the connection.
[0023] During disassembly, simply pinch the upper part of the movable plate 8 manually to rotate the lower part of the movable plate 8 to the left and right sides, thereby moving the positioning block 9 out of the positioning groove 3. At this time, simply pull the sealing plate 4 upward to quickly disassemble.
[0024] Furthermore, the area of the sealing plate 4 is the same as the area of the upper surface of the connecting seat 1, and the thickness of the movable plate 8 is the same as the lateral opening width of the groove 2.
[0025] By adopting the above technical solution, when the sealing plate 4 is being connected, it can completely seal the upper side of the socket 12, thereby preventing dust from entering the socket 12 and affecting the stability of the electrical connection.
[0026] The movable plate 8 is inserted into the groove 2 and fits tightly with the groove 2, thus making the appearance more neat.
[0027] Furthermore, a pin plug 11 is fixedly connected to the middle of the lower surface of the sealing plate 4, and the pin plug 11 is composed of an outer covering frame and an electrical connection pin inside the frame.
[0028] A socket 12 is provided in the middle of the upper surface of the connector 1, and the size of the pin plug 11 matches the size of the socket 12;
[0029] The inner surface of the socket 12 is uniformly and fixedly connected with pin connectors 13, and the pin connectors 13 correspond to the electrical connection pins inside the pin plug 11.
[0030] By adopting the above technical solution, the pin plug 11 can be connected to the connector 1 via the socket 12;
[0031] The electrical connection pins in the pin plug 11 are connected to each corresponding pin connector 13, thereby ensuring normal power supply after electrical connection.
[0032] Working principle: When using this PCBA board quick-release electrical connection structure, firstly, during connection, align the pin plug 11 with the socket 12 and insert it. The movable plate 8 will also be aligned with the groove 2 and inserted. The edge of the groove 2 uses the lower inclined surface of the positioning block 9 to push the movable plate 8, which in turn drives the positioning block 9 to rotate through the shaft 7, tilting it to the left and right. At this time, the torsion spring 10 will be pulled to tighten. When the pin plug 11 is fully inserted into the socket 12, the sealing plate 4 completely seals the upper side of the socket 12, thereby preventing dust from entering the socket 12 and affecting the stability of the electrical connection. At this time, the positioning block 9 will be aligned with the positioning groove 3, and the gap in the positioning groove 3 will be filled with dust. This will cause the positioning block 9 to lose its limit, that is, the torsion spring 10 will rotate back to its original position, thereby driving the movable plate 8 to rotate towards the connecting seat 1, so that the positioning block 9 is inserted into the positioning groove 3. Since the upper side of the positioning block 9 is a plane and it is mutually limited and fitted with the positioning groove 3, the connection structure will not be pulled off at will, thus ensuring the stability of the connection. When it is necessary to disassemble after connection, it is only necessary to manually pinch the upper part of the movable plate 8, so that the lower part of the movable plate 8 can rotate to the left and right sides again, thereby driving the positioning block 9 to move out of the positioning groove 3. At this time, the sealing plate 4 can be pulled upwards for quick disassembly. This is the working principle of the quick-release electrical connection structure of the PCBA board.
